Knurled Solid Pins - Solid Pins

SPIROL's Knurled Pins are manufactured with two different knurl types: straight knurls and helical knurls. Unlike a Straight Pin, where retention is provided by the uniform interference between the pin and hole, Knurled Pins are designed to cut into the host. The displacement of the host material into the valleys of the knurls yields more frictional contact area between the Knurled Pin and hole; thus resulting in higher retention. Solid Pins with retention features such as knurls and barbs allow for wider hole tolerances than Solid Pins without retention features (i.e. Straight Pins).
